Which of the following statements about elevation is true?

Elevation indeed affects temperature by influencing the climate of an area. As elevation increases, the atmosphere becomes thinner, and it is less effective at holding heat. This results in cooler temperatures at higher altitudes compared to sea level. In simple terms, every 1,000 meters (or about 3,280 feet) that you ascend in elevation can lead to a temperature decrease of approximately 6.5 degrees Celsius (about 11.7 degrees Fahrenheit).

This effect is significant in areas such as mountains where distinct climate zones exist from the base to the summit, leading to varied ecosystems and biodiversity. Higher elevations can also influence weather patterns and precipitation.

In contrast, other choices suggest that elevation does not impact climate or geography, which is not accurate, as elevation is a critical factor in both. Additionally, measuring elevation from land depth incorrectly implies that elevation could be measured below sea level, which does not align with the conventional understanding of elevation as being above a reference point such as sea level.
